5.6x-1.2x=22
(x-22)+(x-24)+(x-27)+(x-20)=x
解方程5.6x=1.2x+22
1.2x-x=22怎么解?
(X+X)+(X-X)+(X*X)+(X/X)=100
x-4x=102 x-0.8x=22
方程 0.6(x+4)+0.8=1.2x+0.58 11x+42-2x=100-9x-22
(4x+2)/x+(4x-22)/(x-5)=(x-6)/(x-4)+(7x+9)/(x+1)
解方程:60-x=34.5+4x和5.6x+4x=17.28和12(x-2)=3.6和3x-1.2=3.6
1 6*1.2+(x-6)*2=1.4x 2 22-2.9(12-x)1.3x 3 10x+4=12*(x+1/6) 分
x+x=x+15
3X-18=13.2 1.5X-X=6 4X+1.2X=26
(x-22)+(x-24)+(x-27)+(x-20)=x怎么解
